Book Description
The Tennessee Department of Transportation (TDOT) has designed and built integral abutment bridges with prestressed concrete piles for many years. A product of constructing integral bridge abutments is that the piles supporting the structure are exposed to lateral deflections, which come mainly from thermal expansion and contraction of the bridge structure. TDOT funded a project in which the University of Tennessee, Knoxville investigated the effects of the lateral displacement of four 14 inch square prestressed concrete piles that were driven into virgin clay soil. The tests involved full scale lateral loading each of the four prestressed piles; each pile supported a simulated integral bridge abutment. After each pile was driven into the ground, the model abutment and a "pulling slab" were cast on top of the pile. Leaving one foot of pile exposed between the abutment and the ground, University personnel instrumented each pile with strain gages on that exposed surface. The tests then included a basic testing regime of lateral displacements that depended on incremental displacement and time rate of loading. During the tests, moments, deflections, and shears were recorded at the pile-abutment interface. LPILE is a program that uses a finite difference analysis to calculate the behavior of a pile. While the piles in the field were not instrumented below the surface of the ground, LPILE was used to develop moment versus depth diagrams. Also the analysis evaluated shear and displacement versus depth graphs. LPILE was evaluated on its ability to predict the values measured at the pile abutment interface in the field tests and the consistency with which LPILE located maximum values and inflection points. The LPILE analyses were crude approximations of measured values.

Basics of Foundation Design
Author: Bengt Fellenius
Publisher: Lulu.com
ISBN: 1365824004
Category : Technology & Engineering
Languages : en
Pages : 488
Book Description
The "Red Book" presents a background to conventional foundation analysis and design. The text is not intended to replace the much more comprehensive 'standard' textbooks, but rather to support and augment these in a few important areas, supplying methods applicable to practical cases handled daily by practising engineers and providing the basic soil mechanics background to those methods. It concentrates on the static design for stationary foundation conditions. Although the topic is far from exhaustively treated, it does intend to present most of the basic material needed for a practising engineer involved in routine geotechnical design, as well as provide the tools for an engineering student to approach and solve common geotechnical design problems.
